You received another letter from Client Services, and something feels off. A big bold warning at the top demands immediate payment, though smaller text below mentions your dispute rights. When you called for proof, the representative brushed you off and pushed a payment plan instead.

Who Is Client Services, Inc.
Client Services, Inc. is a debt collection agency based in St. Charles, Missouri, operating since 1987 across the automotive, financial services, healthcare, and retail industries.
- Also Known As: Client Services, Inc. (CSI)
- Address: 3451 Harry S Truman Blvd, St. Charles, MO 63301-4047
- Phone: 800-521-3236 | (800) 521-3236 | +1 800-521-3236 | 8005213236
- Founded: 1987
Client Services markets itself around “Midwestern values” and voice analytics compliance monitoring. Federal court filings describe a different pattern of conduct. The company primarily collects charged-off consumer accounts on behalf of banks, retailers, and healthcare providers rather than originating its own credit.
In our practice, we pull the original account documentation on every Client Services file. Chain-of-custody records often reveal whether the agency actually holds the right to collect on a purchased account.
We also cover other agencies, including Viking Client Services, Credit Bureau Collection Services, Augusta Collection Agency, Best Service Company, and Credit Adjustment Bureau. Client Services itself operates multiple U.S. locations plus a facility in Costa Rica.

If a call comes from a different number, verify it traces back to this same agency before responding. Collectors sometimes work through multiple outsourced call centers.
Client Services lists its principal address in St. Charles, Missouri, and the letter you received should reference this same address or phone number. A letter or call citing a different company name for the same alleged debt is worth verifying independently before you respond.
Why Is Client Services Calling You
Client Services is calling you because a creditor assigned or sold your account to them for collection. The company works across several industries. The original creditor could be a credit card issuer, retailer, healthcare provider, or auto lender.
Getting a call does not confirm the debt is valid or that you owe the amount stated. In our practice, we advise clients to request written validation before discussing any payment. A phone call alone gives you no proof of what the collector claims you owe.
If Client Services already sent a letter, read the entire document, including any text below bold headlines. That smaller text often contains your legal rights. Skipping it is exactly what federal lawsuits accuse the company of encouraging.

Federal Lawsuits Against Client Services
Yes. Client Services has been named as a defendant in multiple federal FDCPA lawsuits.
- Kalmenson v. Client Services, Inc., 1:17-cv-02977 (E.D.N.Y. 2017): class action alleging unfair or deceptive debt collection practices.
- Himes v. Client Services, Inc., 12-cv-321-PB (D.N.H. 2013): alleged the company sent a misleading letter and transferred the debt without honoring a validation request.
- Suxstorf v. Client Services, Inc., 2:17-cv-00043 (E.D. Wis. 2017): class action alleging FDCPA violations tied to confusing settlement letter language.
- Lantry v. Client Services, Inc., 4:18-cv-01694 (E.D. Mo. 2018): alleged the company placed a warning above required legal disclosures and failed to clearly identify the creditor.
When we open a Client Services file, we pull the letter format and compare it against these prior allegations. A warning positioned above validation language is the same pattern courts have already scrutinized. If your letter shows that layout, save it exactly as received.
Is Client Services a Scam
Client Services, Inc. is a real, licensed debt collection agency. Licensed does not mean every tactic is legal.
Court filings allege the company used letter formatting that buries required disclosures. In at least one case, filings allege the company continued collection efforts after a consumer requested validation.
In our experience, we check the Missouri Secretary of State’s business registry on every scam inquiry. A licensed, active registration does not excuse the specific conduct alleged in these lawsuits.
Has Client Services Been Banned by the FTC
No. Client Services has not been banned by the FTC.
The absence of an FTC ban does not mean the company operates without scrutiny. Multiple consumers have pursued private FDCPA lawsuits instead.
The Consumer Financial Protection Bureau and the Missouri Attorney General both accept consumer complaints against licensed collectors. If Client Services has contacted you improperly, filing with these agencies preserves a record even outside a lawsuit.
Frequently Asked Questions About Client Services
Is Client Services Incorporated a legit company
Yes, Client Services, Inc. is a licensed debt collection agency operating since 1987. Legitimacy as a business does not excuse the specific tactics alleged in federal lawsuits.
What if their letter had warnings above the legal disclosures
This formatting has been the subject of federal litigation, including the 2018 Lantry lawsuit. Photograph the entire letter to preserve the layout as potential evidence.
I sent a validation request but they kept calling, is this legal
Continued collection after a validation request may violate the FDCPA. The Himes lawsuit alleged Client Services did exactly this. Document every contact that follows your request.
What counts as proper debt validation
Proper validation includes the original creditor’s name, the amount owed, and proof the agency has authority to collect. A form letter restating the balance alone does not satisfy this requirement. Ask specifically for the account-transfer documentation if the debt has changed hands more than once.
Can I sue Client Services if they violated my rights
Yes, generally within one year of the violation. You may recover statutory damages up to $1,000 per lawsuit. Actual damages and attorney fees are also available if violations are proven.
How do I stop Client Services from contacting me
Send a written cease-and-desist letter by certified mail. After they receive it, the FDCPA limits contact to confirming they will stop or notifying you of specific legal action.
Where do I report problems with Client Services
File complaints with the CFPB, the FTC, and the Missouri Attorney General. Reference the Kalmenson, Himes, Suxstorf, or Lantry lawsuits if your experience matches those allegations.
How does Client Services compare to other collectors you cover
Every agency has its own pattern of complaints and litigation. See our coverage of Account Services phone tactics for a comparison with another agency using similar collection methods.
